  • *For hollow shaft type, the permissible radial load is the value at the distance from the flange-mounting surface.

Note

  • Self locking does not work.
Radial Load and Axial Load

Permissible Torque When Installing Gearheads

The permissible torque when combined with a motor is listed in the "Specifications" section.
Calculate the permissible torque when installing gearheads using the following formula.
Use the values for conductive efficiency in the table below to calculate.
Conductive efficiency at start-up is lower than rating, so please take care when selecting.

Note

  • The transmission efficiency in the table above is the value at normal ambient temperature. The transmission efficiency of the gearhead varies depending on the ambient temperature.
    Care should be taken when using in a low-temperature environment, as the transmission efficiency will drop along with the output torque.

Calculating the Permissible Radial Load for Hollow Shaft Type

When the end of the load shaft being driven is not supported by a bearing as shown in the figure below, calculate the permissible radial load using the following formula.
(This mechanism is the most demanding state in terms of radial load.)

For 4GN□RH

\(\begin{align} \text{Permissible Radial Load} \ W [\mathrm{N}] = \frac{59.5}{59.5 + Lp} \times 295 \ [\mathrm{N}]^{\ast} \end{align}\)
*295 [N]:
Permissible Radial Load at the Flange-Mounting Surface Position
 

For 5GN□RH

\(\begin{align} \text{Permissible Radial Load} \ W [\mathrm{N}] = \frac{70}{70 + Lp} \times 400 \ [\mathrm{N}]^{\ast} \end{align}\)
*400 [N]:
Permissible Radial Load at the Flange-Mounting Surface Position
 

For 5GE□RH

\(\begin{align} \text{Permissible Radial Load} \ W [\mathrm{N}] = \frac{68.5}{68.5 + Lp} \times 645 \ [\mathrm{N}]^{\ast} \end{align}\)
*645 [N]:
Permissible Radial Load at the Flange-Mounting Surface Position
 

For 5GU□RH

\(\begin{align} \text{Permissible Radial Load} \ W [\mathrm{N}] = \frac{68.5}{68.5 + Lp} \times 645 \ [\mathrm{N}]^{\ast} \end{align}\)
*645 [N]:
Permissible Radial Load at the Flange-Mounting Surface Position
 
Lp [mm]: Distance from Flange-Mounting Surface to Radial Load Point
